I cook fried sausage piroshki on kefir quite often. The recipe for a non yeast dough is very easy and fast, the dough does not require long rising. The filling for such Russian piroshki is also as simple as possible: it is enough only to grind all the ingredients and mix them until homogeneous consistency. Piroshki on kefir are very tasty, fluffy and appetizing. After frying, the dough is crunchy and airy, while the filling remains as juicy as possible. Any high-quality sausage is suitable for the recipe. Choose tomatoes not too juicy, fleshy varieties. Hard cheese, greenery or mushrooms fried with onions will significantly enrich the taste of the filling. Therefore, focus on your taste and choose what you like more.
